Air Shower NAS-204 is a controlled entry system used in cleanrooms to remove dust and particulate contamination from personnel and materials before they enter sterile environments.
It acts as a contamination barrier between non-controlled and controlled zones.
Air showers are essential because:
Humans introduce dust, fibers, and microbes into cleanrooms
Even microscopic particles can damage sensitive production
Pharmaceutical and biotech environments require strict cleanliness control
Without air showers:
Product contamination increases
Batch rejection rates rise
Regulatory compliance risks increase
Air Shower NAS-204 is used for:
Cleanroom entry contamination removal
Personnel decontamination before gowning
Material transfer cleaning
Sterile environment protection
Maintaining ISO 14644 compliance
Personnel or materials enter chamber
Interlocking doors seal entry zone
High-velocity HEPA-filtered air activates
Air dislodges particles from surfaces
Contaminants are captured by filtration system
Cleaned subject exits into cleanroom
High-velocity air jets (30–60 sec cycle system)
HEPA filtration system
Automated interlocking doors
Stainless steel cleanroom-grade build
Adjustable airflow cycle control
Low particle turbulence design
Pharmaceutical manufacturing cleanrooms
Biotechnology laboratories
Healthcare sterile environments
Semiconductor fabrication units
Food processing industries
Research & development facilities
Use Air Shower NAS-204 when:
Cleanroom contamination must be strictly controlled
Personnel or materials enter sterile environments
FDA / GMP / ISO compliance is required
High-risk contamination environments exist
Production quality depends on particle-free conditions
ISO 14644 → Defines allowable airborne particle limits in cleanrooms
GMP → Ensures controlled, repeatable, contamination-free manufacturing
FDA & USP → Ensures pharmaceutical-grade safety, sterility, and validation standards
Without these controls, product safety and regulatory approval may fail.
What is Air Shower NAS-204 used for?
It removes particulate contamination before cleanroom entry.
How does an air shower work?
It uses HEPA-filtered high-velocity air to dislodge and remove particles.
What is the cycle time of Air Shower NAS-204 ?
Typically 30–60 seconds.
What filtration is used?
HEPA filtration system.
Is it required in cleanrooms?
Not always mandatory, but widely used for contamination control.
Can it remove microbes?
It removes particles and may indirectly reduce microbial contamination.
Air Shower NAS-204 is a high-performance cleanroom contamination control system designed to remove dust and particulate matter from personnel and materials before they enter controlled environments. It uses HEPA-filtered high-velocity air jets to dislodge contaminants within a 30–60 second cycle, helping maintain cleanroom integrity and reducing the risk of product contamination.
